SPOOL.

Application filed January -to various steps or processes such as bleaching, dyeing, and the like; and the present device is intended to provide a spool for facilitating the carrying out of these various steps or processes. The present device may be of perforated or foraminous construction to alow the chemicals, water, air etc. to pass freely through the walls of the spool. It includes not only the stationary walls of the spool, but certain other elements which temporarily increase the perimeter of the spool while the thread or yarn is being wound thereon, and which may be retracted after. the thread or am has been wound, in order to allow the ody of thread or yarn to slacken in order to loosen it to permit the various chemicals or water to pass between the various turnsof the thread or am in order to efiectively treat all portions t iereof, notwithstandin the fact that a considerable quantity of the thread or yarn iswound in a compact body. These retracting members are adapted to be held in extended position while the thread or yarn is being wound upon the spool, so that it may be wound with a slight tension in regular layers to avoid twisting and snarling of the turns of thread; and after a sufficient quantity of thread or yarn has been wound upon the spool the retracting members may move inwardly in order "to release the tension upon the body of thread or yarn and allow it to loosen while being subjected to various treatments, in order that the liquids may affect the entire surface of the different turns of thread or yarn and in order that the total body of thread or yarn may temporarily shrink if the process causes this result. After the thread has been subjected to the treatment in liquid baths, and in some cases to hot air for drying, the retracting members may be again forced outwardly to tighten the body of thread and they may be held in this position while the thread is being unwound from the spool in order that the same will not become tangled during the rewinding operation, While the thread or yarn is on the spool, various fluids, heat etc. may be forced to pass through all portions of the body of thread or 22, 1926.

yarn. I also provide simple means for holdi ing the retracted members in their outer position and for simultaneously revolving the spool either to wind the t-hread'thereon, or to unwind the thread therefrom.

Figure 9 is apartial longitudinal sectional view of the form shown in Figure 8, and

Figure 10 is a cross sectional view showing still another form of the invention in which the retracting members may lie flush with the periphery of the spool.

Referring first to the form of the invention shown in Figures 1 and 2, the spool consists of a cylindrical body 1 which is made foraminous by the provision, of a series of apertures 2 arranged at close intervals throughout the wall of the cylinder 1. The ends of this cylinder are flared outwardly at 3 and the edges are rolled to provide a rim 4. In this form of the invention the retracting members 5 are adapted to move radially of. the cylinder in ll ln lln slots 6 extending lengthwise of the cylinder and they are adapted to be prevented from falling within the cylinder by means of-l-ips 7 arranged at each end of the retracting memhers. these lips being adapted to rest against the outer surface of'the flared portions 3 of y the spool when the retracting members are in their inner position, as shown in Figure 1. To prevent the retracting members from falling out or away from the cylinder, I have provided lateral flanges 8 which lie within the cylinder and are wider than the slots 6 so that the retracting members will be limited in their outward movement by the engagement 5 'of the flanges 8 with the perimeter of the cylinder 1. Each retracting member includes a vertical wall 9 which moves radially of the cylinder within the slot 6. At the right of Figure 1 I have shown a chuck member for extending the retracting members and for holding one end of the spool while it is being revolved, and it will be understood that a similar member will be provided for the opposite end of the spool the same as in Figure 3. 'This chuck member consists of a head .10 which may be carried on asuitable shaft and the forward end is frnstro conical shape as shown at 11 in order to be inserted into the end of the spool. The smaller end of this frustro conicalmember is of slightly less diameter than the circle formed by the several flanges 8, when the retracting members are in their inner positions. When this chuck member is inserted into the end of the spool and a similar member is inserted into the opposite end of the spool, the frustro conical portions will engage the several flanges 8 and force the retracting members outwardly. This will project the latter members approximately to lo the dotted line position shown in Figure 2, and while the parts are in this position the chucks 10 together with the spool, may be re volved, and the thread or yarn will be wound on the projecting edges of the retracting '15 members. These members will increase the peripheral dimension of the spool during the winding operation so that the yarn or thread may be wound upon these members with sufii-.

cient tension to lay the thread or yarn in regu- MI lar layers upon the spool. After the thread or yarn has been wound upon the spool'the chucks 10 are withdrawn endwise, whereupon the retracting members may move radially inwardly in relation to the spool and this will permit the body of thread or yarn to slacken and thus permit the several layers to loosen or. separate suflioiently to allow the entire-body of thread or yarn to be treated throughout all portions. The spool with the body of thread fill or yarn may then be Subjected to various baths for bleaching or dyeing and to hot air treatment, the apertures in the spool permitting the various fluids to pass through in order that all portions of the thread or yarn 00 may be thoroughly treated. After the thread memos or yarn has been passed througlrthe different processes, the chucks 10 may be again inserted end'wise into the spool in order to force the retractible members outwardly'and place the body of thread or yarn again under tension. In this condition the spool may be revolved to unwind and remove the thread or yarn.

In Figure 3 I have shown a modified construction wherein the retractible members 1.1 have an ear 12 at one end pivoted by means of a pin 13 to the spool at one end. and the opposite end of the retractible member has a projection 14 for engaging against the outer surface-of one end of the spool to prevent this end from dropping entirely into the spool. The retractible member is tapered lengthwise as shown in Figure 8 in order that when its free end is swung outwardly by the chuck 10 the outer surface of the retractible member will remain parallel with the axis of the spool. Alternate retractible members are shown with their pivots in alternate position, that is to say, while the retractible member 11 is.

shown pivotcdat the left hand end of the spool in Figure 3, theretractible member 15 is shown pivoted at, 16 to the right hand end of the spool;-

this way alternate retractible mcn'ibers 1nay be pivoted at opposite ends of the'spool so that the free ends of one set of re traetible members will be engaged by the righthand chuck while" the corresponding ends of the alternate retractible members will he engaged by the left hand chuck 10. This device is usedin the same manner as the form shown in-Figures 1 and 2.

" In Figures 4 and 5 I have shown another form of the invention in which the spool iprop er remains the same but the retractible member, in addition to the vertical wall 17 radially disposed in relation to the spool, and the inner flange 18 for limiting the outwardmovement of the retractible member, has an arcuate plate 19 lying outside of the spool "and on which the. thread or yarn is adapted to be wound. These plates 19 pro vide larger surfaces for engagementof the thread or yarn and I prefer to provide these plates with a series of apertures 20 throughout their surfaces in order to permit fluids to pass through these plates to reach all portions ofthe yarn or thread. In this form the inner flanges 18 limit the outward radial movemcnt of the rctractible members, and the plates 19 limit the inner radial movement. The same type of chu ks as shown in Figures 1 to 3 may be used for holding and rotating this type of spool. H

In Figure 6 I have shown retractible members adapted to be used in the same manner as in Figure 4, but in this form the outer plate 21 is provided with a longitudinally corrugated plate 22 also provided with apertures 23. The object of thisform is to pro vide a member which will engage the yarn at many points and at the same time allow the ill) Jun

fiuid to reach all portions of the yarn or thread by flowing along the grooves of the corrugated plate and throughthe apertures 23.

In Figure 10 the construction is modi'tied, to the extent that the cylinder wall is provided with a number of indentations 2-1 ex tendinglengthwi'se thereof in which the outer plates 19 of the retractible members may be received so that the outer surfaces of these plates lie flush with the periphery of the cylinder when the retractible members are in their inner position.

In Figure 7 the retractible members are shown as comprising rods 25 extending lengthwise of the spool and the ends of these rods are bent downwardly at right anglesand thence turned inwardl at 26 within the wall of the spool. These ent ends of the rods prevent the retractible members from moving out the spool and the retractible members may move in and out a distance corresponding with the space between the rod portion 25 and the surface of the spool as shown in Figure 7. The same type of chuck may be used in connection with this form of spool as is shown in Figures 1 to 3.

In Figures 8 and 9 I have shown another form of the invention wherein the retractible members may be moved in and out while thespoolis being revolved. in order to allow the fluid to pass between the thread or yarn and the surface of the spool, and in fact through all portions of the thread or yarn. In this form of the invention the retractible r members may consist of radial plates 27 moving in longitudinal apertures 28 in the wall of the spool; and the lips 29 on the ends of the retractible members may Serve to hold them from falling inwardly in the spool the same as in Figure 1. In this case there is a polygonal arbor 30 extending through the spool for supporting the same. This member, which is shown as square in cross section in the drawing, may be revolved, and when in the position shown in Figure 8 the member 30 carries one of the retractible members on its top surface and the weight of the spool and thread forces the retractible member radially outwardly in relation to the spool so that the thread or yarn at this point is lifted up from the surface of the spool as shown at 31. As the member 30 turns it will cause the spool to slowly revolve and as the next flat surface of this member comes into the upper position it will engage the next succeeding retractible member and lift it, at the same time permitting the first one to drop back into retracted position. In this manner the spool is revolved by the member 30 and the retractible members are one at a time moved in and out to work the thread or yarn and allow fluid to pass through all portions.
